connection with liquid measuring and cooling devices which can bereadily installed and used in connection with the so called coolerscommonly used to cool charged liquids where they are retailed. I

The novel faucet is adapted to dispense the same kind of liquid from oneor two containers; or to dispense one liquid from one container; or todispense a mixture of two different liquids from separate containers.

The complete apparatus comprises a measuring vessel a movable piston insaid vessel adapted to be actuated by the liquid; means for alternatelyadmitting liquid to the vessel at opposite ends or sides of said piston;the novel dispensing faucet; and suitable pipe connections between thefaucet and the measuring vessel and the liquid containers.

I will explain one practical form of the invention as illustrated in theaccompanyiug drawings, and summarize in the claims the essentialfeatures and combinations of parts which I desire to protect.

In said drawings Figure 1 is a part side elevation and part centralvertical and longitudinal section of the faucet.

Fig. 2 is a longitudinal horizontal section thereof.

Fig. 3 is a detail section similar to Fig. 2 showing the faucet adjustedin another posi tion. 7 r Fig. 4 is a detail diagrammatical plan view ofthe complete apparatus, parts being broken away.

Fig. 5 is a detail section on the line 5-5, Fig. 1. r

Fig. 1. c a Fig. 7 is a horizontallongitudinal section of a modificationof the faucet.

In the embodiment of the invention illustrated in the drawings thefaucetcomprises a main body 1, having a reduced rear portion 1 and anintermediate enlarged externallythreaded shank portion 1 which isadapted to fit in an opening in the wall W to which the faucet isattached, said shank having an annular flange 1 at its front adapted toabut against the front of the wall to which the faucet is attached, andthe faucet secured to this wall by means of this flange and a 'nut 1screwed on the threaded portion 1 Near its front end the faucet has avertically disposed valve chamber 1 in which is fitted a preferablytapered valve 2 which may be held closely but yieldingly to its seat bymeans of a spring washer 2 and a nut 2 screwed on the reduced lower endof the valve. 7 v

The valve chamber 1 has four preferably equi-distant ports 8, 4, 5 and 7Port 3 communicates with a passage 3 leading first upwardly and thendownwardly through the forward goose-neck end 1 of the body. Preferablythe bottom 3 of the inner curve of the neck of the passage 3 lies abovethe top of the other fluid passages in the faucet, for

a purpose hereinafter explained.

The port 4 communicates with a return passage 4-. which extendsrearwardly through the body and shank and into the part 1, and therecommunicates with a lateral outlet 4 which may vbe connected by a pipejoint 4, or other suitable means to a pipe t hereinafter referred to; ip w The port 5 communicates witha supply passage 5 which extends backthrough the body and shank to an outlet 5 in part 1, which outlet may beconnected by a pipejoint 5 to a pipe 5 hereinafter referred to.

.Port 5 also communicates with a supply passage 6 which extends throughthe body and shank to another lateral outlet 6 which may be connected bya pipe joint 6 to a pipe 6. The forward ends of the passages Fig. 6 is adetail section on the line 6-6,

6? and 5" may unite at the port as indi- 1 cated. The port 7communicates with a retur valve 2 shown in Fig. 3, one of the valve i'of the faucet and in front of the wall TV ports establishescommunication between passages 4F and 5 6 whilethe other valve portestablishes communication between the passages 7 and 3 Interposed in thepassage 5 near the front part of the body is a stop cock 5 which may bereadily formed by boring a conical valve seat in the body 1 and fittinga similarly tapered stop cock 5 therein, as in dicated in the drawings.Similarly passage 6? is provided with a stop cock 6 Norm'ally'these stopcocks 5 and 6 should be kept in open position (as shown in Figs. 2

and 3) so as not to obstruct the flow of fluid from the passages 5 and6; but'either of these stop cocks may be closed at will,

for apurpose hereinafter specified.

Between the stop cock 5 and the opening 5", passage 5 is pr ovided'witha vent 5" closed by apet cook 5 Similarly between the stop cock 6? andthe opening 6, passage 6 is provided with a vent 6" closed by a pet cook6 H a Y v The main valve 2, stop cocks 5 6 andpet cocks 5 6 are alllocated in the main body and are all readily accessible.

The complete apparatus adapted to dispense at each operation apredetermined quantity of liquid, for instance, one pint, which isaccomplished by employing a meastiring vessel having a piston which isactuated by the liquidso at each operation of the device a predeterminedquantity of liquid is delivered, V

The measuring vessel 8 (see Fig. 4) is preferably formed of a metalcylinderclosed at itsends by heads 8 and 8", and within this vessel 8 isaslidable piston 8*, which may be of any suitable construction, adaptedto prevent liquidpassing by said piston from' one end of the vessel tothe other.

The head 8 of the vessel h a's an opening connectedby'pipe et tothefaucet opening The head 8 has an opening connected by pipe? with faucetopening 7 The opei'iing 5 of" the faucet is connected by pipe 5 with anydesired liquid supply, or container, L; and opening 6? is similarlyconnected by pipe 6 to another liquid supply or container L.

The pipes 5, 6 may be connected intermed ate thecontainers L and thefaucet with the cooling coils (not shown) in an ice box (not shown) sothat the liquid will be cooled before reaching the vessel 8..

When the parts are in the position shown in Fig, 2 liquid can flow fromcontainers L, L through pipes 5, 6 and supply passages-5, 6 p'ort2passage 7 and pipe 7 into the end 8* of the measuring vessel 8, andforce the piston 8 thei'ein'toward the end 8, At the 'same time liquidwill be expelled from vessel 8thr'ough the pipe l and through returnpassage l port 2 to discharge sage 3 and be'discharged. hen the "piston8 reaches the end Sethe flow of liquid to and from the vessel 8 will'bestopped; and if the vessel is adapted todeliver a pint "only a"pi'nt offluid will have been discharged. If the valve 2 is then turnedvto theposition indicated in Fig. 3, liquid will then flow as described fromthe containers L, L to the port 5 and thence'through port 2 passage at,and pipe st into the end .S of

the container and force piston 8 toward the end 8", and liquid will besimultaneously expelled from vessel 8 through the pipe 7, return passage7, port Z and discharge passage 3 7 v If the vessels'L, L contain thesame kind of liquid then only one kind of liquid will be dispensed. Ifthe vessels L, L contain different kinds of liquid,'then a mixture ofthese liquids can be dispensed at each operation; and the relativequantities of such liquids inthe mixture can. be controlled by partiallyclosing one or the other of the pet cocks 5*", 6 so that any desiredmixture of two liquids can be readily obtained.

The liquids are forced from the containers to the faucet by airpressure, so that the pressure of fluidin the passages 5, 6 will beuniform, and the liquids from one passage 5 or 6 will not flow into theother.

In the modificationshown in Fig. 7 ill-' stead of the two supplypassages 5, 6 only one passage 9 is shown, which communicat'es with anoutlet 9 at the'rear end. of the faucet which outlet inay be connectedby a pipe joint 9 with a pipe 9 which may be connected to a liquidsupply or container.

'lVith such a faucet all the liquid would pass from the containerthrough the passage 9, but would be directed alternately to oppositeends of the measuring vessel, no stop cock would be required, and onlyone rent 9 and pet cock 9 would be used.

It will be understood that under normal conditions the piston 8 willtravel from one end of thevessel to the other, and this vessel isof suchsize that it will contain in addition to the piston say one pint ofliquid, and when liquid is admitted into one end of the vessel alikeamount is simultaneously expelled from the other end thereof, by the thevalve 2 a quarter turn to establish com-V vessel. When the pistonreaches either end of the vessel its movement is'arrested; thus stoppingthe inflow and outflow of liquid, until the valve 2 is again shifted soas. to admit liquid into that end ofthe vessel against which the pistonhas stopped, and simultaneously permit escape of liquid from the otherend thereof. I

when a container is emptied the passages and pipes may be fully orpartially filled with gas or air, which must be vented before a properamount of liquid can be withdrawn. By opening the pet-cocks 6* or 5* anyair or gas collected in the passages can be vented. These cocks shouldbe closed as soon as liquid flows therethrough.

As above stated, the major parts of the apparatus may be placed withinthe ordinary ice box or cooler, and all the parts which have to bemanipulated by the operator are on the front of the faucet outside ofthe box.

The pet-cocks 5 6* enable the operator to determine which container isempty, if two containers, from both of which liquid is being withdrawn,are simultaneously used. If one container becomes empty before the otherair would follow, and would be evidenced by a hissing noise when thevalve 2 is opened. If this occurs the operator by opening the pet-cockscan easily determine whether the container connected with passage 5 or 6is empty, because. only gas or air will escape from the pet-cock in thepassage connected with the empty container,

while liquid will escape from the pet-cock of the passage connected withthe full container. If, for example, the operator should find gasescaping from passage 5 he should close stop cock 5 and can continuew1thagain withdrawn from both containers Similarly if container L shouldbecome exliausted the passage 6 can be closed and a full containersubstituted for container L.

When making a change of containers communication between the ports 6 and5 should be closed by the stop cock 5 or 6 to prevent siphoning orby-passing of fluid from one container to the other.

In operation it is only necessary to give munication between one end ofthe vessel 8 and the atmosphere through the discharge outlet 1; at thenext quarter turn of the valve communication is established between theother end of the vessel and-the atmosphere. Therefore the operator bysimply giving the valve successive quarter turns can draw as-manysuccessive pints, or measures of liquid as he wishes, To preventdripping of liquid from the open faucet passages I make the dischargepassage 3) goose necked with the top of the portion 3* lying above thefluid passages as indicated by the dotted When the apparatus is-firststarted, or

line in passage3 in Fig.1. This prevents any annoyin'gleakage of liquidafter the proper amount of liquid has been discharged from themeasurlngvessel.

. To entirely close communication between- By this invention theoperator while at p the faucet, can withdraw liquid in measured amountsfrom a plurality of containers; can determine which of the containershas become empty; can continue to draw from one container while anotheris being replaced; and has all the valvesand cocks assembled compactlyin one .faucet in plain view and within easy reach. i

A liquid dispensing faucet comprising an elongatedbody provided with a plurality of longitudinal supply and returnpassages, a discharge passage and a valve chamber intermediate thedischarge passage and the supply .and return passages having portscommunicating withall said passages; with a valve in said chamberprovided with ports adapted to establish communication between a supplypassage and a return passage, and simultaneously establish communicationbetween the other return passage and the discharge.

2. A liquidldispensing faucet comprising an elongated body provided withtwo supply and two longitudinal return passages, a discharge passageanda valve chamber intermediate the discharge passage and the supply andreturn passages having ports communicatingwith all said passages; and avalve in said chamber provided with ports adapted to establishcommunication between one supply passage and two of the return passages,and simultaneously establish communication between the other returnpassage and the discharge.

3. A liquid dispensing faucet comprising an elongated body provided witha plurality of longitudinal supply and return passages, a dischargepassage and'a valve chamber intermediate the discharge passage and thesupply and return passages having ports communicating with all saidpassages, and a Ivalve in saidchamber provided with ports adapted toestablish communication between a supply passage and a. return passage,and

chamber provided with ports adapted to establish communication between asupply passage and a return passage, and simul taneously establishcommunication between the other return passage and the discharge andmeans whereby the passages may be vented and the failure of liquidsupply detected; with a liquid supply connected with the supply passage,and a liquid measuring device connected with the liquid return pas- 10sage.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
